TO ALL WHOM IT MAY CONCERN:

Be it known that I, GEORGE V. COOPER, of Ogeechee, in the county of Scriven, and State of Georgia, have invented a new and useful improvement in Horse-Hoes for cultivating corn and cotton; and I do hereby declare the following to be a full, clear, and exact description of the nature, construction, and operation thereof, sufiicient to enable those skilled in the art to which my invention appertainsto fully understand and use the same, reference being bad to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a plan.

Figure 2 is an inverted plan and Figure 3 is a section taken through the line a: w, fig. 2.

Similar letters of referenceindicate corresponding parts in the several figures.

My inventi'onconsists, first, in forming the hoe in several distinct parts, secured by screw-bolts to a baseplate, so that when the edge of any one of these parts becomes dull, the injured plate may be removed, repaired, and replaced Without interfering with the remaining pieces; second, in providing a metallic sole, which is so secured to the under side of the base-plate as to regulate the depth of the furrow, and thus avoiding the necessity of lifting the plough entirely from the ground when it is desirable to transfer the implement from one point to another without ploughing.

In the drawings, A is the metallic base-plate or frame, on which the central section I and shares O C are secured by screw-bolts passing through the upper and lower plates, on the under face of which they are held by nuts. The central portion B is curved from front to rear, and extends a short distance front and back beyond the shares O O, which are secured at its sides. The front projection of'the central section B forms a point. This extension of the part B adds strength to the structure, and at the same time steadies the plough in the ground, thus preventing its lateral movement. Shoulders a a are formed in the opposite sides of section B, at the base of the projecting point. The shares C C jut against the shoulders a a, and are secured in that position, thus avoiding the possibility of the plough being injured and weakened by roots and stones which might otherwise be forced in between the plough point and shares during its passage through the soil. A narrow sole of metal, D, is so attached on the lower face of the base-plate A to the forward bolt 0 as to turn readily thereon This strip extends beyond the rear end of the central section B, where it is bent upward, and is so secured to the standard of the plough, that by pressure on the handles of theplough the point is raised. thuscontrolling the depth of the furrow. By thus constructing ploughs or horse-hoes, much time, labor, and expense are saved. As has been stated, when any portion of the hoe is injured or requires sharpening, it may be readily detached, repaired, and replaced without the necessity of removing the entire implement to the shop. Each piece may be duplicated and supplied to the farmer at a small cost, when compared with the price of a new plough, constructed in the ordinary manner.

Having thus described my invention, the following is what I claim as new, and desire to secure by Letters Patent:

1. Forming a plough or horse-hoe of four separate sections, viz, base A,-centre plate B, and shares O O, constructed and arranged substantially as described and for the purpose specified.

2. I claim the shoulders 11 a, formed in the opposite sides of the plate B, substantially as described and for the purpose specified.

3. I claim the metallic sole D, secured to the base-plate A, for regulating the depth of the furrow, substantially as described.

To the above specification of my improvement I have signed my hand this 30th day of March, 1867.

GEORGE W. OOOPER.
